For questions about modeling processes from cognitive and neurobiological theories via algorithms and computer simulations, and also about confirming experimental results with theoretical/statistical constructs.

I'm a junior researcher(Life Sciences undergraduate) starting out in computational genetics of neuroscience, and I want to create a Unified Theory/Computational Model of the human brain and all its ...

I've been scanning through the web, looking for some ideas and theories about computational modules of human behavior and personality, but so far all I could find regards to procedural programs and ...

I have read many papers and books about ontologies, and I am trying to figure out that how they are used in a real project. For example, how can the ontology for a soccer player robot can be defined ...

As discussed previously, there are a wide range of models that have been applied to the Wisconsin card sorting task. However, which one is most biologically plausible? That is, uses a realistic model ...

As computational neuroscience has the mainstream on single neuron/network modelling for biochemical aspect, and computational modelling of physiological mechanism of hippocampus for analytic study of ...

ACT-R was the first big cognitive model and excels at modelling human behavioral data quite accurately.
Spaun, which is the world's largest functional brain model, took a lot of ACT-R's insights and ...

There are many different incremental models of the hippocampus and it's role in learning as shown by a quick search. However, have there been any efforts to combine these various models into a single ...

The Neurological Engineering Framework can be used to create systems that use memory in interesting ways. One system (Spaun) is able to memorize (and forget) lists much in the same way as humans do. ...

How much does the SPAUN and the Semantic Pointer Architecture (SPA) that was used to build it take neurotransmitters into account? In the book How to Build a Brain, various inhibitory and excitatory ...

I am a computer science student, and as part of my project, I would like to develop a system that changes the TV channel, increases its volume, etc. by just the thought of it. My primary investigation ...

I am a computer science student [assume I have very little knowledge of the biological part of EEG]. I recently came across the topic EEG and was pretty interested in it. As far as I know, we get an ...

I want to characterize a binary time-series signal x (derived from neuron action potential data) in the frequency domain.
Should I use the FFT of the original signal x, or the power spectrum (FFT of ...

In the first chapter of the book "How to Build a Brain", Chris Eliasmith quickly establishes some criteria which he will use to evaluate Spaun, the cognitive system described in the book. He describes ...

I'm working through How to Build a Brain and I keep getting confused on the relation between Nengo, the Semantic Pointer Architecture (SPA) and the Neurological Engineering Framework (NEF).
Are there ...

In particular, theoretical and computational neuroscience seem to be synonymous with each other. Neuroinformatics at least seems to deal somewhat more with solving things numerically and the usage and ...

I think that certain aspects of ant colony behavior seem almost like economic decision-making in behavior. There are also links between ant colony optimization and features of the brain like selective ...

Are there mathematical models of memory in humans or animals?
I want to know how neuroscientists use mathematics to describe memory in living creatures. How do neuroscientists model memory and show ...

I'm interested in the difference between spike-triggered averaging and reverse correlation.
In some papers (i.e., Schwartz, Odelia, et al) I see the term 'Spike Triggered Averaging'.
In others, (ie ...

How does the human brain calculate velocities? For example, when crossing a road and seeing a car coming towards you, how does the brain actually compute the rough velocity of the vehicle and your own ...

What sort of computations are used for localising sound with the ears, and how does the brain compute the time difference between sounds reaching each ear? I am interested in the specific mechanisms ...
